One cultural method that can be used as a last resort, and which, accord- ing to Mr. Park, has shown good results in Alberta, involves harrowing the crop crosswise to the seeding direction when the seedlings are 5 to 13 cm tall. Harrowing must be done in dry, sunny weather. There are very few insects in Alberta that attack fababeans, but Mr. Park says crops should be watched for three diseases. They are ascochyta blight, a seed-borne disease, which causes stem, leaf and pod spotting; sclerotinia, which is c
